I'm running Weblogic 10.3.4.0_4, Portal 188.8.131.52.0, db server runs Oracle 11g all under Solaris 10 SPARC 64bit.
The problem I'm having is very odd. When I upload a ZIP file to any Portal page (new content page or existing page), then subsequently download it, it is corrupted. The original file decompresses properly though.
If I use WinSCP to copy the file directly to the server and put it in the htdocs directory, then download it direct, the file is fine. Method #1 stores the file in the database, Method #2 , obviously, is stored in the file system.
I've looked at the Oracle DB's alert log, WLS_PORTAL log, apache's error_log and I dont see any error that would indicate the upload is corrupt or a dropped network connection etc.
